In 1582 Edward Kelly, a channeler and some say a charlatan,
claimed he received the Enochian alphabet during a session with pal John
Dee. Kelly says he was told this was the language of the Angels before
the fall of humankind and the Tower of Babel. They worked the alphabet
into a complex magick system that became popular with the 19th century
occultists, including Aleister Crowley, and it continues to be used/practiced
today.
